Diet boxes have become essential in recent years. They work on a simple idea: delivering everything you need to follow a specific dietary program directly to your home.

Their promise? To help you lose weight without hassle. Generally, these boxes include pre-measured portions for each meal, which you only need to supplement with fruits, fresh vegetables, and sometimes dairy products, according to the provided recommendations.

To go even further in support, some offers include monitoring by a nutrition professional, such as a dietitian-nutritionist and a fitness coach. This duo allows for customizing the program to your needs and maximizing your results.

However, not all boxes are created equal. To help you see more clearly, we conducted an in-depth study of the 7 main slimming programs, compared according to 3 criteria.

We evaluate all boxes independently. If you click on one of the links provided, we may receive a commission, without affecting the price or ranking.

Methodology and comparison criteria

To create this comparison, I determined 3 qualitative criteria based on program characteristics. Each criterion is rated out of 5, and the average of the 3 scores determined my final rating and ranking.

1. Nutritional quality of the proposed meals

One of the essential points to consider is the meal content. These come in various forms: freeze-dried sachets, canned meals, or fresh meals. Among them, fresh meals stand out for their higher nutrient density, offering superior levels of essential vitamins and nutrients. This characteristic gives them a privileged place in this comparison.

Additionally, I carefully evaluated the quality of the ingredients used, giving particular value to fresh products from short supply chains or organic farming. This choice highlights not only nutritional qualities but also the environmental impact and traceability of meals. 

When brands specify the source of ingredients, it provides an additional guarantee of transparency and reliability.

Another key criterion is the absence of additives, GMOs, and artificial colorings, ensuring healthier meals that meet the health-conscious consumers’ expectations.

Finally, the diversity of the proposed menus was carefully examined. A varied diet program is essential to avoid monotony and cover all nutritional needs.

The inclusion of specific options, such as dishes suitable for vegetarian or gluten-free diets, reflects particular attention to dietary restrictions and consumer choices.

2. Customer experience

The user experience is not limited to just the content of the boxes but encompasses the entire process offered by the brand.

For example, some companies provide a mobile app. This can be very useful for choosing your menus, tracking weight progress, or even receiving real-time advice. 

The program may also include regular appointments with professionals, such as dietitians or fitness coaches, adding a human and personalized dimension to the support.

Furthermore, motivational tools, like community support groups on social media, reinforce user engagement. These groups, often found on Facebook, allow sharing successes, exchanging tips, or simply finding moral support, which can make a big difference in the success of a weight loss program.

3. Reliability and trustworthiness of the brand

A brand’s reputation plays a decisive role in choosing its box. 

Brands with a long market presence generally inspire more trust, as they demonstrate a certain longevity and ability to evolve with consumer expectations. 

I also considered their presence and notoriety on social networks, looking at their number of followers.

Customer reviews on Trustpilot provide valuable insights into user satisfaction and the quality of meals and service.

Finally, the responsiveness of the customer service was evaluated by sending an email to support. The quicker and more comprehensive the response, the greater the likelihood of each company’s commitment, in my opinion.

5. La Brigade de Véro

Founded in 2017 in the Montpellier area, La Brigade de Véro offers fresh meal deliveries, designed to support weight loss or maintenance, while adapting to the specific needs of its clients.

La Brigade de Véro stands out for its 100% homemade dishes, guaranteed to be free of additives and preservatives. The recipes change with the seasons and are made from fresh, local, and sourced products.

A major asset of the brand is its transparency: every ingredient used is traceable, and most products come from the southwest of France. I find this transparency very appreciable, as it offers a guarantee of quality and reliability.

La Brigade de Véro offers a wide range of programs that adapt to each person’s goals and dietary preferences. Among the options available, you can choose, among others:

• A low-carb or fiber-rich program

Breakfasts and snacks are also fresh and sometimes homemade or from small artisanal businesses and often local. They may include artisanal pastries, dairy products, or carefully selected fruits, adding a gourmet touch to the program.

Meal delivery is done once a week in a refrigerated truck, ensuring the freshness of the dishes.

The standard program of La Brigade de Véro provides a caloric intake of 1,200 kcal per day. To meet each client’s specific needs, it is recommended to supplement meals with fruits, fresh vegetables, and dairy products.

6. Comme J’aime

Founded in May 2010, Comme J’aime is a French brand specializing in the delivery of “ready-to-eat” meals to support weight loss. It has established itself as a reference in the field thanks to significant media presence, particularly with television commercials featuring personalities known to the general public.

Comme J’aime offers standardized 7-day programs, including 4 meals a day: breakfast, lunch, snack, and dinner. However, there is little flexibility in the options offered. The only possible customizations concern specific dietary regimes, such as: meat-free, fish-free, vegetarian …

The meals are delivered all at once for the entire program, with no possibility to choose individual meals.

The offer includes 75 different dishes as well as 14 breakfast and snack options. The dishes are made in France, guaranteed to be free from GMOs and preservatives. The meats used are of French origin.

Lunch generally consists of a canned dish and dinner is often lighter, with freeze-dried meals to rehydrate, such as soups or purees. All of them can be stored at room temperature.

The programs offer days at 1,200 – 1,300 kcal, to which it is recommended to add fruits and dairy products to achieve a balanced caloric intake.

In addition to meals, Comme J’aime offers support to guide and encourage its clients:

• A mobile app that allows tracking weight progress, accessing advice, and staying motivated.
• Dietary support provided by nutritionists and weight loss coaches.

However, unlike other brands, Comme J’aime does not offer a community support group on platforms like Facebook. Only an official page is available for brand communication.

The brand enjoys strong visibility on social networks with more than 15,000 followers on Instagram and 103,000 on Facebook.

On the review site Trustpilot, Comme J’aime has an average rating of 3.9/5 based on over 4,800 reviews. The positive points mentioned include the quality of the dishes and the seriousness of the customer service. However, some recurring criticisms mention the high cost of the programs and financial penalties in case of early termination.

Customer service is responsive and answers questions efficiently. However, I particularly noted an aggressive commercial approach, strongly encouraging the purchase of the program.

7. Diet Box

Diet Box is a French brand belonging to the same group as Comme J’aime.

Unlike Comme J’aime, Diet Box allows you to select dishes before finalizing payment, offering customization tailored to each user’s dietary preferences.

The proposed meals are the same as those offered by Comme J’aime and follow a fixed format, but with a well-defined composition: 1 breakfast, 1 prepared lunch dish, 1 snack, 1 soup, and 1 freeze-dried sachet meal for dinner.

In addition to meals, Diet Box offers an initial assessment with a weight loss coach and personalized support provided by a nutritionist, allowing users to be accompanied throughout their program.

With an average rating of 3.1/5 based on 147 reviews, Diet Box receives mixed feedback.

Most clients praise the simplicity and effectiveness of the proposed programs, however, other reviews mention the bad taste of the dishes, the lack of variety in the menus, and recurring delivery issues.

Diet Box lacks visibility on social networks, with only 18 followers and a practically inactive page. However, the customer service is very responsive: despite sometimes being busy, the advisors call back quickly and answer questions clearly.

One of the main advantages of Diet Box, in my opinion, is its competitive price.

Weight Loss Programs: FAQ

Is it possible to lose weight quickly with a weight loss program?

Yes, these boxes, based on a strong caloric deficit, can lead to rapid weight loss. However, losing weight too quickly can be harmful to health and difficult to maintain in the long term. It is better to opt for a progressive and balanced approach.

Moreover, weight gain is often the symptom of an underlying issue: poor knowledge of nutritional needs, altered relationship with food, metabolic imbalances, etc. While weight loss boxes are effective in the short term, they do not address the real causes. This is why weight regain often occurs at the end of the program.

How long should a weight loss program be followed to see results?

It depends on individuals and goals. Results can be visible within a few weeks if the program is well-suited.

What to do if I do not achieve the expected results with a weight loss program?

Weight loss boxes are generally very low in calories. If you are not losing weight, it may be due to excessive consumption of foods outside the planned meals or a metabolic disorder preventing weight loss. In this case, it is essential to consult a healthcare professional for appropriate guidance.

Are weight loss programs safe for health?

Well-supervised and personalized programs are generally safe. However, avoid overly restrictive methods or those not validated by professionals. Restrictive diets are ineffective in the long term, can cause nutritional deficiencies, and promote the development of eating disorders.

How to avoid regaining weight after finishing a weight loss program?

To avoid the yo-yo effect, it is essential to:

• Maintain good eating habits,
• Engage in regular physical activity,
• Work on the relationship with food.

It is also important to adopt new eating habits by listening to your needs, desires, and food sensations, without frustration.

Are weight loss programs suitable for everyone?

No, every individual has specific needs. A program must be personalized based on health status, goals, and lifestyle. This type of program is not recommended for people with eating disorders.

Do restrictive diets in weight loss programs cause nutritional deficiencies?

Yes, overly restrictive diets can lead to deficiencies. It is preferable to choose balanced programs that meet all your nutritional needs. Prepackaged or freeze-dried meals, often used in these programs, are generally low in vitamins destroyed during their preparation. Therefore, it is important to add fresh fruits and vegetables at a minimum.

Should you consult a doctor or nutritionist before starting a weight loss program?

Yes, it is highly recommended. A professional can ensure that the program is suitable for your health condition and goals, thus avoiding any unnecessary risk.
